Title: Improved Base-Thrust Nozzles for Jet Propulsion Engines
IPC: F02K1/28
Filed: 1967-05-31
Abstract: 1,194,716. Jet propulsion nozzles. UNITED AIRCRAFT CORP. May 31, 1967 [June 1, 1966], No. 25197/67. Heading F1J. A supersonic or hypersonic jet propulsion nozzle comprises a base member mounted within the nozzle housing and having a base surface at its downstream end for receiving upstream thrust presuure, so that the flow of fluid around the base member and base surface creates a region of lowpressure downstream of the base surface, and an additional member (a "sting") extending downstream from the base surface into a high-pressure region downstream of the low-pressure region includes means for diverting a portion of the stream of fluid from the nozzle to the low-pressure region to increase the upstream thrust pressure acting on the base member. In Fig. 3, the base member, which may be in the form of a central plug 84, carries a sting 88 extending downstream of the base surface 86. Fluid from a high-pressure region downstream of a shock wave 95 enters the interior 90 of the sting through inlets 92 and leaves it through outlets 94 at a lower-pressure region upstream of the shock wave, where it acts to increase the thrust pressure acting on the base surface 86. In addition, the downstream end surface of the sting 88, being within the highpressure region, is subjected to a high thrust pressure. The sting may be axially movable automatically to adjust the position of the inlets 92 in accordance with variations in the position of the high-pressure region. An annular flange (100), Fig. 4 (not shown), may be provided at the downstream end of the sting 88 to deflect the fluid into the inlets 92. In a further embodiment, fluid from the inlet of the engine or from a region downstream of the turbine or a separate fluid from a pressurized tank or the like is passed through the interior of the sting to outlets at the downstream end of the sting, where it is injected (at supersonic speed, if desired) into a shock region to deflect a portion of the jet flow into an upstream direction to increase the thrust pressure on the base surface. The engine may be of turbojet, ramjet or socket type. Reference has been directed by the Comptroller to Specification 1,072,082.

Filed: 1958-08-08
Abstract: 895,053. Injection moulding machines. KOEHRING CO. Aug. 8, 1958 [March 10, 1958], No. 25571/58. Class 87(2). One half 16 of a mould 15, 16 is carried by a ram 19 and is given a rapid initial closing movement followed by a high pressure final approach and clamping action, the changeover being effected by a sleeve valve 56 which is slidable from the position shown in Fig. 4 wherein pressure fluid (from a pump 91) is supplied through a conduit 48 to a bore 31 within the ram 19, to a position, Fig. 3 (not shown), wherein pressure fluid is also supplied (through ports 51) to the annular end face 38 of the ram 19. In Fig. 4 the sleeve valve 56 is biased in one direction by a spring 84 and is moved to open the ports 51 by fluid pressure supplied by a pump 93 through a solenoid operated valve 94 and conduit 87. During the rapid advance of the ram 19 in its cylinder 21, fluid is drawn in from a supply tank 52 to fill the space 47 behind the ram. When the sleeve valve 56 has moved rearwardly to open the ports 51, bevelled seatings 64, 65 on the valve 56 and housing section 41 are brought into engagement and prevent escape of high pressure fluid from the space 47. Opening of the mould is effected by moving the valve 93 and another valve 92 to their reverse positions. The mould half 16 is carried by a platen 18 secured to the ram 19. Mould half 15 is supported by a die head 17 containing an injection nozzle 14. In a modification, Fig. 5 (not shown), the valve sleeve is moved in both directions by fluid pressure instead of being biased in one direction by spring 84.

Title: Computing device
IPC: G06F15/80
Filed: 1964-06-22
Abstract: 1,059,213. Digital calculators; electric selective signalling. WESTINGHOUSE ELECTRIC CORPORATION. June 22, 1964 [July 5, 193], No. 25689/64. Headings G4A and G4H. Computing apparatus comprises a plurality of gating devices of the NAND type. The circuit shown in Fig. 6 can be used as an adder, or as a logical OR, EXCLUSIVE OR, or AND circuit. The gates 40, 42, 60, 62, 64 are all NAND gates, i.e. they produce a zero output if and only if all inputs are one. Thus if a GATE A pulse is applied to the gate 60 as well as binary signal #A (the inverse of A), the output will be A. Thus, if A = 1 the output will be a one. The flip-flop 44 (and similarly 50) is such that a zero signal applied to terminal 47 will produce a zero output on terminal 45 and a one output on terminal 46. Similarly a zero signal applied to terminal 48 will produce the opposite outputs. One input signals have no effect on the flip-flops, which are said to be " set " when a zero appears on their upper terminals 45, 51 and " reset " when a zero appears on their lower terminals 46, 52. Reset signals can also be applied as shown to the flip - flops. However, neither flip - flop will change its state unless the applied signals include a clock pulse CKS or CKC. Fig. 7 (not shown) shows the sequence of signals applied to the circuit when it is used for addition purposes. This sequence covers one binary digit place of each of the numbers being added, and the same circuit is used for each digit place in sequence. Initially at time T1 the sum flip-flop 44 is reset and at time T2 the carry from the previous digit stored in the flipflop 50 is applied as an input to gate 40 via NAND gate 64. All other inputs to gate 40 are ones, since S = 1 and there is no gate A or gate B pulse applied to the gates 60, 62. Thus the sum flip-flop will be set if the previous carry was a one. At time T3 the carry flip-flop 50 is reset. At time T4 a gate A pulse is applied to gate 60, thus applying A, the required digit of the first operand, to the gates 40 and 42, one at least of which is enabled, as CK1, CK2 pulses are provided, the outputs from the gates 62, 64 must both be one, and either S or S is one. Thus the state of the sum flip-flop 44 is changed if the digit A is a one, and if this is so and the pulse is applied through the gate 42, i.e. flipflop 44 was already set, then the carry flip-flop 50 is also set, a zero being applied at input terminal 53. A similar operation takes place at time T5 in respect of the corresponding digit B of the second operand. The sum and carry digits are then available at the output terminals 45 or 46, 51 or 52 of the two flip-flops 44, 50. By use of other sequences of pulses (Figs. 8 and 9, not shown), the circuit will produce an output at the terminals 45 or 46 of flip-flop 44 corresponding to the logical operations, AND, OR or EXCLUSIVE OR performed on digits A and B. The circuit is stated to be of particular use in a parallel network type of computer as described in Specification 1.026,888.
